TYPICAL OBJECTS OF TYPE Period

This type represents the most general time interval that corresponds to a sequence of Single Period objects.
For example, a Period object may represent the time interval constructed by putting together in a consecutive manner a period of 1 month followed by a period of 3 days.

Due to the fact that the type Single Period is a direct subtype of Period, it is possible to treat a Single Period object as if it were a Period object.

Similarly, due to the fact that the type Step is a direct subtype of Single Period and hence a subtype of Period, it is possible to do the same with a Step object.
Therefore, simply entering the text %3M suffices to create a Period object that represents 3 months.
Similar simple entries are %3D for 3 calendar days, or %1B{US} for 1 business day wrt the US calendar, or %1B{US|MF} for 1 business day wrt the US calendar and the Modified Following date bump convention.
Period objects containing sequences with up to two Single Period objects are treated as trivial objects
Therefore, one may simply enter the text %2Y3M to represent a composite interval of 2 years followed by 3 months.
Conventions may be also added, such as %2Y{US}3M{DE} or %2Y{US|MF}3M{DE}
